St. Louis (KMOX)–If your Tuesday  communte takes you on  I-70 over the Blanchette Bridge in either direction, you might want to consider an alternate route in the morning because of a temporary shutdown.  MoDot will begin closing lanes in both directions at 9:00 a.m., with all lanes in both directions closed by 10:00 a.m.  This in order to blow up the rest of the steel tress on the Westbound bridge.  By 11:00 a.m., three lanes in each direction will be up and running.
